I have the opposite problem: I close tabs too soon, but history solves that.
I switched back to horizontal tabs because sidebars eat up too much horizontal screen space.
This is a valid reason to switch back, but I'd also like to call out that UX designers need to do more for users with limited horizontal space. Many users rely on split-screen mode to see two windows simultaneously, or maybe three windows simultaneously if they've got a widescreen 21:9 aspect ratio monitor.
For me, tab location is spacial in my mind, and so many years of having them horizontal makes it hard to switch. Somewhere between 25 and 40 I start having trouble finding things at which point I just close them all and start over. I do use the tab drop-down in Firefox, but mostly to more quickly find things I want to close. Also completion in the url bar to find specific open tabs is quite useful.
If you use Firefox's URL bar for this, typing % before your search limits the results strictly to open tabs.
The sweet spot for me is vertical tabs that autohide into a narrow strip of icons until hovered over (like Edge or certain firefox CSS tweaks)
>Vertical tabs are not a standard. Chrome does not have them natively. Safari does not have them at all.

Google Chrome added vertical tab support in 2026 Q2 and Safari has had them even longer.
